Beáta Megyesi, the main organizer of the HistoCrypt 2018 (http://www2.lingfil.uu.se/histocrypt2018/index.phtml), is working at a project called DECODE and funded from the Swedish government. There, a huge amount of original cryptograms, the transcribed versions, and context information are already available. She worked together with historians, computer linguists, image processing experts, and cryptographers. In the future also cryptanalysis tools (like CrypTool 2) will be incorporated. Currently DECODE (https://stp.lingfil.uu.se/decode/search/) can only be used via invitation.

That’s not really true.
1. CrypTool (CT) is the most wide-spread e-learning program for cryptography and cryptanalysis. This is its main purpose.

2. There are many cryptanalysis methods implemented in CrypTool 2 (CT2). Hill climbing is already there and most of George Lasry’s methods will follow. Also automated cryptanalysis of homophones is under construction, so we hope it’s going to become the tool of choice for analyzing classical ciphers.

Thereof, 22 implement classical ciphers. And thereof are 21 functions helping to analyze classical ciphers. For instance, Lasry’s analysis of the double column transposition is already built in (see the template Cryptanalysis\ Classical\ Dictionary attack on the Double Columnar Transposition Cipher). [This list on the CrypTool portal website is a bit behind the current status and also has some flaws: E.g. Fialka is listed under classical cryptanalysis instead of under classical cryptography in the English list. The German list is ok in this case.]

4. CT2 also aims to become the framework of choice for modern cryptanalysis. Currently, it has 21 functions for modern cryptanalysis and 28 modern ciphers implemented.

5. Attached is a screenshot from the current Nightly Build of CT 2.1, showing the 24 templates built-in and ready to run to do classical cryptanalyis. The templates itself as well as the sources can be enhanced by everybody.
